On the underlying surface the patterns are created from photographs of spears made from wood and shark teeth. On the top or outer curve the patters are from pressed flowers preserved in the herbaria and not usually on display. The design of the form used to make the shapes is inspired by this beautiful shell necklace from the Pacific which is part of the ethnographic collections and currently on display in the Cook and Scoresby room of the museum. The very textured inner curve also has gold applied using the tradition technique of keum boo.
The piece has been oxidised and then highlights polished back up.
